Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739686, here are decompositions:

13 + 8739673 = 8739686
19 + 8739667 = 8739686
79 + 8739607 = 8739686
103 + 8739583 = 8739686
157 + 8739529 = 8739686
223 + 8739463 = 8739686
337 + 8739349 = 8739686
349 + 8739337 = 8739686

Showing the first eight; more decompositions exist.
